Arsene Wenger was last night caught up in a second controversial incident after Arsenal's humiliating Carling Cup exit.

The Gunners are still investigating the clash in which Nicklas Bendtner ended bloodied after being head-butted by team-mate Emmanuel Adebayor.

And off the pitch, boss Wenger was caught in the crossfire as Spurs players Robbie Keane, Jermain Defoe and Dimitar Berbatov sprayed the TV interview area with champagne while he was giving his post-match interview.

The players were in the Spurs dressing room as Wenger's interview was being taped. But as TV pictures were replaying a recorded post-game chat with Spurs assistant Gus Poyet, the trio believed it was the Uruguayan who was still being interviewed.

They burst into the interview room and let fly with the bubbly, only to realise it was Wenger instead of Poyet. Arsenal last night sought to play down the incident but Spurs technical director Damien Commolli still saw fit to apologise to Wenger.
